Dungs 46050-3 Modulating Actuator Motor 120VAC DMA 30B120, 30 Second 90 Degree Stroke
The DUNGS DMA Actuator drives from 0° to 90° via a 4 - 20 mA input signal. It can move in any direction and stop anywhere over the entire 90° stroke. The field adjustable stroke is factory set at 90° and the position is factory set at 0°.
The DMA is available in three different speeds: 6s, 12s, or 30s. The DMA has one independent, field adjustable auxiliay SPDT switch and two field adjustable limit switches.
During any power interruption, the actuator will remain stationary. After power is restored, the position is determined by the controller input signal. However, if the 4 - 20 mA signal is interrupted and the DMA is still powered, the actuator will drive fully CW, which will close the DUNGS DMK butterfly control valve.
4 - 20 mA feedback can be used to drive a slave motor (3 actuators maximum in parallel).
APPLICATIONSWhen mounted on the DUNGS DMK butterfly control valve, the DMA is used to automatically modulate the amount of natural gas, butane, propane and/or air supplied to the burner.
Compliant to the EU Low Voltage and EMC Directive
